Description

Technical Field

[0001] The utility model relates to the technical field of composite aluminum materials, in particular to a fireproof composite aluminum material. Background Art

[0002] Composite aluminum is a new type of door, window and curtain wall building material that combines aluminum alloy with polymer thermal insulation materials. Through this combination, a thermal insulation interlayer is formed in the center of the aluminum alloy profile, thereby achieving the purpose of heat preservation and energy saving. Among them, composite aluminum plates solve the problem of high product cost and narrow application range due to the complex flash welding process and the need for large equipment;

[0003] Most of the current composite aluminum panels are multi-layer structures with a plastic core material in the middle. When actually spliced, from a cross-sectional perspective, the plastic core materials between two adjacent composite aluminum panels are in contact with each other, which causes the fire to spread rapidly when a fire occurs. In addition, since the composite aluminum panels are stacked layer by layer, their overall impact resistance is not high. Utility Model Content

[0004] The purpose of the utility model is to provide a fireproof composite aluminum material to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fireproof composite aluminum material, comprising a core material and an aluminum plate, wherein two aluminum plates are provided, each of the aluminum plates has a folded edge on its surface, two adjacent edges are welded, a receiving cavity is formed between the edge and the aluminum plate, the core material is provided between the two receiving cavities, and a first flame retardant plate is provided between the core material and the aluminum plate;

[0007] The core material includes a middle plastic plate and a surrounding plastic plate. The surrounding plastic plate is a U-shaped structure. The surrounding plastic plate is just embedded in the accommodating cavity. The middle plastic plate is embedded in the surrounding plastic plate. The gap between the middle plastic plate and the surrounding plastic plate is separated by a flame retardant structure.

[0008] Preferably, the flame retardant structure is formed by bonding four second flame retardant panels end to end, and the second flame retardant panels are attached to the side walls of the middle plastic panel and the surrounding plastic panels.

[0009] Preferably, four of the second flame retardant plates are perpendicular to and bonded to the surface of the first flame retardant plate, and the second flame retardant plates are arranged parallel to the corresponding retaining edges.

[0010] Preferably, an anti-corrosion protective film is bonded to the surface of the aluminum plate.

[0011] Preferably, a fluorocarbon resin baking varnish layer is provided on the surface of the anti-corrosion protective film.

[0012] Preferably, the surface of the fluorocarbon resin baking varnish layer is provided with an outermost protective film.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model forms a container with a single-side opening through four retaining edges and an aluminum plate. When the two containers are buckled together, the core material inside can be sealed, so that when actually spliced, the core materials between two adjacent composite aluminum materials will not contact each other, thereby preventing the spread of fire. In addition, for the core material, the middle plastic plate and the surrounding plastic plates are separated by the first flame retardant plate and the second flame retardant plate. When the fire enters the containing cavity through the damaged retaining edge or the aluminum plate and burns the surrounding plastic plates, it can prevent the fire from further burning the middle plastic plate. In addition, the containing cavity is a closed space, thereby achieving a high fireproof performance.

[0015] 2. The utility model forms a container which is combined with two aluminum plates, and supports the two aluminum plates from the inside of the container through four second flame retardant plates which are perpendicular to each other and connected end to end. The first flame retardant plate attached to the surface of the aluminum plate increases the overall thickness of the aluminum plate, and cooperates with the four second flame retardant plates which are vertically arranged on the surface of the first flame retardant plate to increase the overall impact resistance of the aluminum plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model provides a fireproof composite aluminum material, including a core material 1 and an aluminum plate 2, wherein two aluminum plates 2 are provided, and a rib 3 is folded on the surface of each aluminum plate 2, and two adjacent ribs 3 are welded to form a receiving cavity 4 between the rib 3 and the aluminum plate 2, and the core material 1 is arranged between the two receiving cavities 4, and a first flame retardant plate 5 is arranged between the core material 1 and the aluminum plate 2, and the core material 1 includes a middle plastic plate 11 and a surrounding plastic plate 12, and the surrounding plastic plate 12 is a U-shaped structure, and the surrounding plastic plate 12 is just embedded in the receiving cavity 4, and the middle plastic plate 11 is embedded in the surrounding plastic plate 12, and the gap between the middle plastic plate 11 and the surrounding plastic plate 12 is separated by a flame retardant structure.

[0022] See also Figure 2 The two ribs 3 corresponding to the two aluminum plates 2 are bonded together by an adhesive. At this time, the core material 1 completely fills the space inside the accommodating cavity 4, and the ribs 3 can cover the sides of the core material 1. This ensures that when the aluminum plate 2 is installed on the wall, the two adjacent core materials 1 will not contact each other, thereby preventing the spread of fire.

[0023] The flame retardant structure is formed by four second flame retardant panels 6 bonded end to end, the second flame retardant panels 6 are attached to the side walls of the middle plastic panel 11 and the surrounding plastic panels 12, the four second flame retardant panels 6 are perpendicular to and bonded to the surface of the first flame retardant panel 5, and the second flame retardant panels 6 are arranged parallel to the corresponding retaining edge 3.

[0024] See also Figure 3 First, the four second flame-retardant panels 6 can cooperate with the two first flame-retardant panels 5 to form a closed space, thereby completely isolating the middle plastic panel 11 inside the surrounding plastic panels 12. This makes it difficult for the flame to continue to enter the closed space and burn the middle plastic panel 11 even if the surrounding plastic panels 12 are burned. Secondly, the second flame-retardant panels 6 are perpendicular to the first flame-retardant panels 5. For the first flame-retardant panels 5, the second flame-retardant panels 6 can cooperate with the retaining edge 3 in the middle area of ​​the accommodating cavity 4 to support the aluminum panel 2 and the first flame-retardant panel 5, thereby increasing the overall impact resistance of the aluminum panel 2.

The outermost protective film 9 can provide waterproof and scratch resistance.
